Analysis of the health condition and the abiotic environment of forest stands in the territory of the Jizerské hory Mts, Czech Republic

Abstract

The paper sets out to analyse the causality of the abiotic environment and health condition of forest stands for the territory of the Jizerské hory Mts natural forest region (hereinafter NFR). To reach an understanding of the potential impact of SO 2 and NO x pollutants and climate stressors on forest ecosystems, a considerable amount of data on the abiotic environment needs to be acquired, also for territory in which such measurements of the data have not been made. This is why the data on temperature conditions, water balance, solar radiation, ozone concentrations and deposition flows of sulphur, nitrogen and hydrogen ions were derived through model applications and interpolation techniques. Geostatistical methods should be used instead based on the application of multidimensional methods. The health condition analysis of the forest stands (as manifested by defoliation) and parameters of the forest stands’ abiotic environment is carried out by applying simple and multidimensional regression and correlation analyses. The cluster analysis helped determine spatial distribution of five areas of potential disposition to the damage of forest stands. The results of a multiple correlation and regression for each potential disposition area were put together to form a model explicating the forest stands defoliation status.
